Given that women live in those cultures, let's say Buenos Aires in particular, how do they deal with it?
It's not uncommon for a young man to acknowledge an older woman with a piropo. When this happened to me, I accepted that this is something Argentine men do in the city. They aren't aggressive nor do they expect the woman to respond in any way.
One situation stands out. Alito and I were walking from my apartment to the milonga at Lo de Celia. I held his arm while walking down the street as always. A young man directed a piropo to me from the other side of the street. This says something about Argentine men who feel no hesitation to express themselves to strangers in public. It's a part of life in the city of Buenos Aires.
Piropos are abundant between dances in the milongas. Some are published in B. A. Tango magazine for all to enjoy. The women who contribute them certainly do.
